Nose tackle Josh Brent will not be permitted to be on the Dallas Cowboys' sideline for the remainder of the season, team and league sources said Tuesday.
The Cowboys and officials in the NFL's offices were unaware that Brent -- who is on the reserve/non-football injury list after being charged with intoxication manslaughter two weeks ago in the car crash that killed teammate Jerry Brown -- would be on the sideline Sunday during the game against the Pittsburgh Steelers in Dallas. Both the team and the league agree that it was not appropriate, sources said.
Meanwhile, a judge ordered Brent to wear an electronic ankle monitor, and also modified conditions for his continued release, lowering his bond from $500,000 to $100,000 during his Tuesday court appearance.
Brent also was ordered not to consume alcohol or drive until he has a valid Texas license, and he was fitted with a SCRAM device that will detect any alcohol consumption. The judge warned Brent that any violation of these terms will result in him being immediately returned to jail.
Heath Harris, the first assistant district attorney, said he expected Irving police to file a case against Brent with prosecutors this week. Prosecutors hope to present their case to a grand jury before the end of the year, Harris said.
Several of Brent's teammates urged him to attend Sunday's game, but coach Jason Garrett, who spoke to Brent the day before the game, didn't know about it until pregame warm-ups.
The game already had begun when Garrett realized Brent was on the sideline, and owner Jerry Jones didn't know until he saw Brent on television.
Garrett said Monday that Cowboys players were following the wishes of Brown's mother, Stacey Jackson.
According to sources, Brent went to the game somewhat reluctantly. He was driven by a teammate on injured reserve who told Brent that all of his teammates wanted him to be there. Once Brent became aware that his presence was sparking a national debate, he left Cowboys Stadium in the third quarter.
Brown, a Cowboys practice squad player, was killed in a one-car accident involving Brent the day before Dallas' Dec. 9 game against the Bengals.
At the memorial service for her son, Jackson told the players to care for Brent and keep him involved with the team as much as they could. The organization has expressed support for Brent since the accident, while making it known that it does not condone drinking and driving.
"It becomes a real sensitive topic to a lot of people when you're in a public place like the game," Garrett said Monday. "There were no bad intentions other than to support Josh as part of our football team. This is a game and you need to be here. That's what our players wanted to convey to him and they really encouraged him to come to the game. I thought Josh handled it beautifully the way that he came and then when he felt like there were some issues he felt the right thing to do was to leave. But we're going to support him in every way that we can. We also will be sensitive to this kind of issue."
